What Does EPC Rating E Mean? How Bad Is It?
If your EPC shows a band E rating, your home is below average for energy efficiency. Around 19% of English homes are rated E, and they are disproportionately older properties with solid walls. The honest truth: E is not great, but it also means you have significant room for improvement and could save £500-800 per year by reaching band C.
EPC Rating E means your home has an energy efficiency score of 39 to 54 out of 100. Band E is below the UK average and is the current legal minimum for rental properties. A typical E-rated home costs £1,600 to £2,200 per year to heat. Around 19% of English homes are rated E, most commonly older properties with solid walls.
EPC band E at a glance
Where does E sit on the EPC scale?
The EPC scale runs from A (most efficient) to G (least efficient). Each band corresponds to a range of SAP scores out of 100:

What does an E rating actually tell you?
An E-rated home typically has several of the following characteristics:
Walls
Often solid walls (stone or solid brick) with no insulation. This is the single biggest factor in most E-rated homes. Solid walls lose heat roughly twice as fast as insulated cavity walls. Common in homes built before 1930.
Heating
May have an old non-condensing gas boiler, electric storage heaters, or oil heating. Controls are often basic or absent. Some E-rated homes have no central heating at all, relying on individual room heaters.
Insulation and glazing
Loft insulation may be thin or missing entirely. Single glazing may still be present on some or all windows. Floor insulation is almost always absent. The home loses heat from every surface.
Bills
A typical E-rated home pays around £2,100-£2,500 per year on energy bills (at Q2 2026 Ofgem rates of 5.74p/kWh gas and 24.67p/kWh electricity). That is £500-900 more than the Ofgem typical household bill of £1,641, and up to £1,000 more than a C-rated home.
What types of homes are typically rated E?
E ratings are not random. Certain property types are far more likely to be in band E:
Victorian and Edwardian terraces
Solid brick walls, original single-glazed sash windows, tall ceilings that are expensive to heat. These make up a huge proportion of E-rated housing stock.
Rural stone cottages
Thick stone walls (which are surprisingly poor insulators), often off the gas grid and reliant on oil or LPG heating. Beautiful but expensive to run.
Pre-war semis and detached homes
Built before cavity walls became standard. Large surface areas (especially detached homes) mean more heat loss. Often have partial or no loft insulation.
Flats with electric heating
Older purpose-built and converted flats with electric storage heaters score poorly on the EPC because electricity is more expensive than gas per kWh of heat delivered.
What does E mean for selling or renting?
For homeowners selling
There is no legal minimum EPC for selling. But an E rating will put off some buyers. They will factor in the cost of improvements, and mortgage lenders may be less generous with lending on poorly rated homes.
Making even modest improvements before selling (getting to D or ideally C) can increase the sale price by more than the cost of the work.
For landlords renting
E is the current MEES minimum. You can legally let an E-rated property today. But from October 2030, the minimum rises to band C.
Going from E to C is a bigger jump than D to C. It typically requires more substantial (and more expensive) improvements. Start planning now. See our landlord compliance guide.
How to improve from E to C
Moving from E to C means gaining at least 15-30 EPC points. That is a bigger leap than D to C, and usually requires a combination of insulation and heating improvements. Here are the most impactful measures:
| Improvement | Typical cost | EPC points | Annual saving |
|---|---|---|---|
| Cavity wall insulation* | £0-£500* | 5-12 | £180-£290 |
| Solid wall insulation (internal) | £5,000-£10,000 | 8-15 | £200-£400 |
| Solid wall insulation (external) | £8,000-£14,000 | 8-15 | £200-£400 |
| Loft insulation (0 to 270mm) | £300-£600 | 4-8 | £100-£200 |
| Double glazing (replacing single) | £4,000-£8,000 | 3-8 | £80-£150 |
| Condensing boiler (replacing old) | £2,500-£4,000 | 5-10 | £150-£300 |
| Air source heat pump** | £4,500-£7,000** | 10-20 | £200-£450 |
| LED lighting + draught-proofing | £80-£280 | 2-5 | £85-£145 |
* Cavity wall insulation is often free through GBIS/ECO schemes. ** Heat pump cost shown after £7,500 BUS grant (full cost £12,000-£14,500). EPC point gains vary by property. Sources: Energy Saving Trust, BRE SAP methodology.
A realistic path from E to C
For a typical E-rated Victorian terrace (solid walls, old boiler, thin loft insulation):
Loft insulation (6 pts, £400) + condensing boiler (8 pts, £3,000) + internal wall insulation (12 pts, £7,000) + LEDs and draught-proofing (3 pts, £200) = 29 points for about £10,600.
With ECO4 or Warm Homes Plan funding, the wall insulation and boiler could be fully or partly grant-funded, reducing your out-of-pocket cost to £2,000-£5,000.
Grants for E-rated homes
E-rated homes are actually prioritised for grant funding. Most schemes target the worst-performing homes first, which means you are more likely to qualify:
ECO4 (Energy Company Obligation)
Fully funded insulation, heating, and ventilation improvements for low-income households and those on certain benefits. ECO4 specifically targets homes rated E, F, or G. The scheme aims to bring these homes up to at least band D, and ideally C. If you are on benefits or a low income, this is the first scheme to check.
Warm Homes Plan
The government's flagship programme launching in 2026. It will provide grants and low-interest loans for home energy upgrades, with the worst-performing homes (E, F, G) getting priority. Expected to fund insulation, heating upgrades, and more.
Read our Warm Homes Plan guide for the latest.
Great British Insulation Scheme (GBIS)
Free insulation for qualifying homes. E-rated homes qualify on the "general eligibility" route (council tax bands A-D, any income). Also available to all homes in bands E-G regardless of council tax band.
Check eligibility on our grants page.
Boiler Upgrade Scheme (BUS)
£7,500 towards an air source or ground source heat pump. Particularly impactful for E-rated homes because a heat pump can gain 10-20 EPC points, and replacing an old inefficient boiler has the biggest effect on both your score and your bills.
Learn more in our heat pump guide.
Grants can be combined
You can often use multiple schemes together. For example, GBIS for free cavity wall insulation + BUS for a heat pump grant + ECO4 for loft insulation. A good installer or energy advisor can help you stack these to minimise your costs.
Our honest take on EPC band E
E is not where you want to be. Your home is losing more heat than it should, your bills are higher than average, and if you are a landlord, you are going to need to act before 2030. There is no sugar-coating that.
But there is a silver lining: E-rated homes have the most to gain. The improvements that take you from E to C will save you £500-800 per year on energy bills. That is real money. Over 10 years, that is £5,000-£8,000 in savings, which often covers the cost of the work (especially with grants).
The biggest barrier for most E-rated homes is solid wall insulation. If your home has solid walls, this is the single most impactful (and most expensive) improvement. But it is also the one most likely to be grant-funded. Check your eligibility for ECO4 and the Warm Homes Plan before paying out of pocket.
Start with the cheap wins (loft insulation, LEDs, draught-proofing) while you plan the bigger work. Every point gained is money saved.
Check your specific property
Every E-rated home is different. A Victorian terrace with solid walls needs a completely different approach from a 1960s flat with electric heating. Your EPC certificate lists specific recommended improvements with estimated costs and savings.
Our free tool pulls your actual EPC data, shows every recommended improvement, and helps you identify the most cost-effective path to band C. It takes 30 seconds.
